What is the scientific method?
the kind of study that records info/behavior in real world settings without intervention or manipulation
What is Naturalistic Observation?
subtle changes and wording that can lead to bias in how the participant responds
What is the wording effect?
A symmetrical, bell-shaped curve that describes the distribution of many types of data with most scores falling near the mean.
What is a normal curve?
The percentage of scores that are lower than a given score.
What is the percentile rank?
when a test produces the same result repeatedly under similar conditions
What is reliability?
a survey used to collect data using a self-report, often qualitative and quantitative
What is the survey technique?
organization dedicated to advancing the field of psychology and promoting the application of psychological knowledge to human welfare
What is the American Psychological Association?
The tendency for extreme or unusual scores or events to fall back or regress towards the average.
What is regression to the mean?
A probability distribution with two distinct peaks (or modes), suggesting the presence of two separate subgroups or processes within a dataset.
What is bimodal distribution?
for sure, 100%, numerical evidence
What is empirical evidence?
pre-determined questions asked in the same way and order to every participant
What is a structured interview?
scientific study of mental processes and behavior
What is psychology?
A distribution where most data points cluster towards the lower end of the scale, with a few extreme scores extending towards the higher end.
What is positive skew?
A statistical statement of how likely it is that a result (such as a difference between samples) occurred by chance, assuming there is no difference between the populations being studied.
What is statistical significance?
What is peer review?
includes an in-depth examination of a single, individual, or group phenomenon, - usually rare
What is a case study?
people believe that they knew something was going to happen after it already occurred even if they didn't predict it beforehand
What is hindsight bias?
When most of the data points are clustered towards the higher end of the scale, with a long tail extending towards the lower end.
What is a negative skew?
The strength of the relationship between two variables. The larger the effect size, the more one variable can be explained by the other.
What are effect sizes?
What is falsifiable?
a measurement tool used in surveys to scale peoples' attitudes, opinions, or perception
strongly agree -> strongly disagree
what is the likert scale?
What is the Social Desirability Bias?
When most of the data points are clustered towards the higher end of the scale, with a long tail extending towards the lower end.
What is standard deviation?
A statistical procedure for analyzing the results of multiple studies to reach an overall conclusion.
What is meta analysis?
